- In ionic bonds, electron pairs are shared between atoms. In covalent bonds, atoms are electrostatically attracted towards each other.
- Ionic bonds occur through the interaction between cations and anions. Covalent bonds occur through the interaction of neutral atoms.
- Ionic bonds are the strongest type of chemical bond. Covalent bonds are quite weak.
- Metallic elements tend to form ionic bonds. Non-metallic elements tend to form covalent bonds.
